10 years agobackports: formalize struct sock sk_data_ready() backport with SmPL
Luis R. Rodriguez [Tue, 15 Apr 2014 21:03:31 +0000 (21:03 +0000)]
backports: formalize struct sock sk_data_ready() backport with SmPL

Commit 676d2369 by David removed the skb->len arguments passed onto
the struct sock sk_data_ready() callback. This was done as its racy,
a few drivers were passing 0 to it, and it was not really used.
By removing it the raciness is addresed but to backport this we are
going to have to deal with the races as-is on older kernels. This was
merged as of v3.15:

mcgrof@ergon ~/linux-next (git::master)$ git describe --contains 676d2369
v3.15-rc1~8^2~10

Since this is not a define or static inline we can't easily replace this with
the backports module or header files, instead we use SmPL grammar to generalize
the backport for all use cases. Note that in order to backport this we won't
know what older kernel drivers were using before this change, it could have
been 0 or skb->len for the length parameter, since we have to infer something
we choose skb->len *iff* skb_queue_tail() was used right before it, otherwise
we infer to throw 0.

Adding this SmPL patch to our series only incurs an additional ~9 seconds
on run time code generation.

commit 676d23690fb62b5d51ba5d659935e9f7d9da9f8e
Author: David S. Miller <davem@davemloft.net>
Date:   Fri Apr 11 16:15:36 2014 -0400

    net: Fix use after free by removing length arg from sk_data_ready callbacks.

    Several spots in the kernel perform a sequence like:

        skb_queue_tail(&sk->s_receive_queue, skb);
        sk->sk_data_ready(sk, skb->len);

    But at the moment we place the SKB onto the socket receive queue it
    can be consumed and freed up.  So this skb->len access is potentially
    to freed up memory.

    Furthermore, the skb->len can be modified by the consumer so it is
    possible that the value isn't accurate.

    And finally, no actual implementation of this callback actually uses
    the length argument.  And since nobody actually cared about it's
    value, lots of call sites pass arbitrary values in such as '0' and
    even '1'.

    So just remove the length argument from the callback, that way there
    is no confusion whatsoever and all of these use-after-free cases get
    fixed as a side effect.

    Based upon a patch by Eric Dumazet and his suggestion to audit this
    issue tree-wide.

worker on a file until it has determined that a rule being
evaluated applies to a file. This does however mean that all files

CPU usage without having us to ramp up on the number of threads

more threads to account for the fact that a Coccinelle thread will
stop working on a file if it had little or nothing to do on a file.

Possible work improvement: see how we can do away with tmp files

mcgrof@ergon ~/linux (git::master)$ git describe --contains 3493f69f4
v3.11-rc2~18^2~2

We backport them with our own respective set of helpers. Each new data
structure that gets an attribute group needs a respective SmPL set of
rules for the transformation, specially if they were introduced in
different kernel versions, which in this case we have two which were.
By using SmPL we can automatically backport the collateral evolutions
moving forward for *any* driver that makes use of these group
attributes on both data structure we are addressing in these SmPL
patches. This is a great example of the level of atomicity that we
want to ideally strive to reach for backporting, as it lets us
automatically backport a collateral evolution through grammer for
*any* device driver we backport, and lets us be lazier.

We provided backports of introduction of the group attribute onto
two data structures:

  * struct class: added via commit d05a6f96c
  * struct bus_type: added via commit fa6fdb33b

v3.12-rc1~184^2~89

This patch generalizes the backport the introduction of the group
attribute to each data structure into separate SmPL patch files.
One change the SmPL patches pick up on was #ifdef'ing over the
init_foogroup_attrs() calls which would only have been introduced when
ATTRIBUTE_GROUPS_BACKPORT() was used, which *is* #idefd's.

The changes that added the new APIs are below, the respective commits
for each data structure change are documented on each SmPL patch.

backports: revert unification of cocci files

This optimization was introduced by Johannes to help with
performance before we had parallelism. With parallelism
we get better results by splitting rules up. Also some
feedback from Julia on this:

===
I don't think this is a good idea.  You would have to be careful about
naming.  And You may lose on some performance benefits of the prefiltering.
Suppose you have an easy semantic patch that references function A and a
hard semantic patch that references function B.  The hard semantic patch
specifically contains one rule that is very complicated but that does not
use B.  That very complicated rule will now be applied to the 5000 files
that use A as well as to the 3 files that use B.  So you get a big
performance slowdown.

backports: backport define of SIOCGHWTSTAMP

Ben added ioctl support for the unprivileged SIOCGHWTSTAMP
which is designed to just get the configuration, unlike
SIOCSHWTSTAMP which requires you to set it and only after
it returns the configuration.

Since we are carrying over a small addition to a UAPI header
without carrying it over completely (we use copy-list to
carry over full UAPI headers) its worth making a design note
about this.

We carry UAPI headers for backports to enable compilation
of kernel / driver code to compile without any changes. If
it so happens that a feature is backported it can be added
here but notice that if full subsystems are backported you
should just include the respective full header onto the
copy-list file so that its copied intact. The strategy on this
patch can be used to either backport a specific feature or
to just avoid having to do ifdef changes to compile kernel
or driver carried over by backports.

Userspace is *not expected* to copy over backports headers
to compile userspace programs, userspace programs can
and should consider carrying over a respective copy-list
of the latest UAPI kernel headers they need in their
upstream sources, the kernel the user uses, whether with
backports or not should be able to return -EOPNOTSUPP if
the feature is not available and let it through if its
supported and meats the expected form.

In this particular case if userspace tries to send the
SIOCGHWTSTAMP they'd end up with -ENOTTY.

backports: backport dev_consume_skb_any()

dev_consume_skb_any() was added by Eric via commit e6247027e
added as of v3.14 to help do analysis on the different reasons
why an skbs are free'd in particular to let us know how many get
dropped or consumed. The new dev_consume_skb_any() spawned the
inception of an optimization for dev_kfree_skb_irq() which was
implemented through __dev_kfree_skb_irq() which dev_kfree_skb_irq()
now uses. We could have taken advantage of both if kernels had
exported raise_softirq_irqoff() but they don't and as such we
can't reimplement that on backports as it stands right now.

If we'd be building backports in-kernel we could just take the
new implementation of __dev_kfree_skb_irq() as raise_softirq_irqoff()
would be available and we could reap the benefits of the change.
That implemention can be seen as a reference - for now - here:

http://drvbp1.linux-foundation.org/~mcgrof/patches/2014/04/11/pend-2014-04-07.patch

For older kernels for now we just use the singular old version of
dev_kfree_skb_irq() and dev_kfree_skb_any().

    We need to separate the two causes to get better diagnostics

    __dev_kfree_skb_irq() is slightly optimized to remove one

10 years agobackports: bump kernel requirements for drivers that use s2mps14.h

backports: bump kernel requirements for drivers that use s2mps14.h

These depend on include/linux/mfd/samsung/s2mps14.h which
other mfd drivers / platform code can depend on, skip
unless we backport all the dependencies which we don't
right now.

The affected drivers are:

  * REGULATOR_S2MPS11
  * REGULATOR_S2MPA01
  * REGULATOR_TPS65217

The mfd files which we don't backport that uses this are:

  * drivers/mfd/sec-core.c
  * drivers/mfd/sec-irq.c

10 years agobackports: add GRO_* enums, and its new gro_result_t typedef

backports: add GRO_* enums, and its new gro_result_t typedef

This backports commit d1c76af9e added by Herbert which added the first
enums and then commit 5b252f0c2 added by Ben which gave the enums a
label and then pegged a typedef onto these. This backports these commits
in a forward compatible way upkeeping the introduction and then the
typedef. In order to make this work we use make backported code use
enums with the BACKPORT_prefix but upkeep the same values, this lets
us declare the typedef and peg it to a similar set.
